The **Weight of a Semicircle Concrete Slab**calculator computes the weight or mass of a semicircular shaped concrete slab based on the radius (r), the depth (D) and mean density of concrete.

**INSTRUCTIONS:** Choose units and enter the following:

- (
**D**) Depth of Semi-circle slab - (
**r**) Radius of the semi-circle slab

**Semi-circle Mass (M)**: The calculator returns the weight in pounds. However, this can be automatically converted to compatible units (e.g. kilograms, tons, metric tons) via the pull-down menu.

The formula for the volume of a semicircle is:

M = ½•π•r²•D

where:

- M = Mass or weight of semi-circular concrete slab
- D = Depth of Slab
- r = radius of the semicircle
